I-nickel-titanium memory wire

I-Nitinols isetyenziswa ngokubanzi kwizixhobo zonyango, i-aerospace, izixhobo zombane, kunye namashishini eemoto kwaye ziyaziwa ngemisebenzi yazo ekhethekileyo kunye nokusebenza okugqwesileyo. I-nickel-titanium alloy, ekwabizwa ngokuba yi-memory alloy, inconywa njengempumelelo kwisayensi yezinto ngenxa yempembelelo yayo yememori kunye ne-superelasticity.

Okokuqala, impembelelo yememori yocingo lwe-nitinol ibavumela ukuba babuyele kwimilo esetwe ngaphambili xa ishushu, into ebaluleke kakhulu kwizixhobo zonyango. Ngokomzekelo, xa kusetyenziswa i-stents ye-cardiac, i-nickel-titanium alloy stents inokunyanzeliswa kumaqondo obushushu aphantsi ukuze kube lula ukufakwa emzimbeni, kwaye emva koko ibuyele kwindlela yokuxhasa imithambo yegazi kubushushu bomzimba, nto leyo ephucula kakhulu izinga lokuphumelela. ukusebenza kunye nesantya sokubuyisela isigulane.

Okwesibini, iipropathi ze-superelastic ze-nickel-titanium alloy wire zenza ukuba zikwazi ukuchacha ngokukhawuleza emva kokuguqulwa ngaphandle kokuguqulwa okusisigxina. Le propathi iyenza yomelele kwaye ithembekile kwi-aerospace kunye nezixhobo zombane. Ngokukodwa kwiindawo ezishukumayo eziphezulu okanye ezinoxinzelelo oluphezulu, ucingo lweNiTi lunokumelana nemijikelo yoxinzelelo oluphindaphindiweyo ngaphandle kokulahlekelwa yimpahla yabo yomatshini.

Ukongeza, i-Nitinol ine-biocompatibility efanelekileyo kunye nokumelana nokubola, okwenza ukuba ifaneleke ngokukodwa ukusetyenziswa kwintsimi yezonyango. Ucingo lwe-Nitinol alukwazi ukuqhagamshelana nezicubu ze-biological ixesha elide ngaphandle kokugatywa kodwa nokugcina ukusebenza okuzinzile kwiindawo ezinomswakama kunye ne-corrosion.

Isishwankathelo, ucingo lweNitinol, olunempembelelo entle kakhulu yenkumbulo, ukuqina okuphezulu, ukuqina, kunye nokuhambelana kwebhayoloji, iye yaba lukhetho olufanelekileyo lwezicelo ezahlukeneyo ezifunayo kwaye ikhuthaze uphuhliso kunye nokuveliswa kwamashishini amaninzi.

iinkcukacha zemveliso

Impembelelo yememori

Uphawu olubalulekileyo lweNitinol. Esi siphumo sivumela intwasahlobo ye-Nitinol ukuba ibuyele kwimilo esele isetyenzisiwe phezu kwesiphumo esithile seMemori kwiqondo lokushisa. Umzekelo, kutyando olungephi, izikhokelo zeNitinol kunye neestents zinokukhubazeka kumaqondo obushushu aphantsi kwaye zifakwe ngokulula emzimbeni. Xa ukushisa komzimba kufikeleleke, ezi zixhobo zibuyela kwimo yazo yangaphambili, zibonelela ngenkxaso efunekayo okanye umsebenzi wesikhokelo, ukuphucula kakhulu ukuchaneka nokukhuseleka kwenkqubo.

hyperelasticity

I-Nitinol wire inokukhawuleza ibuyele kwimeko yabo yangaphambili emva kokuguqulwa okukhulu ngaphandle kokuguqulwa okusisigxina. Olu phawu luyimfuneko kwiindawo zokungcangcazela okuphezulu kunye noxinzelelo oluphezulu. Kwishishini le-aerospace, imithombo ye-Nitinol isetyenziswe kumacandelo abalulekileyo afana neenjini kunye neenkqubo zokulawula ukunyamezela imijikelezo yoxinzelelo oluphindaphindiweyo kunye nokuqinisekisa ukuthembeka kwenkqubo yexesha elide kunye nokuzinza. Kwizixhobo ze-elektroniki, i-nickel-titanium alloy springs isetyenziselwa izixhumi ezichanekileyo eziphezulu kunye nezitshintshi ezincinci ukubonelela ukuqina kwexesha elide kunye nokuqinisekisa ukusebenza kakuhle kwezixhobo.

I-Biocompatibility kunye nokumelana nokubola

I-biocompatibility egqwesileyo ye-Nitinol iyenza ibe yinto efanelekileyo yokufakelwa kwezonyango. Ayiyi kubangela ukulahlwa komzimba kwaye iqinisekisa ukhuseleko lokusetyenziswa kwexesha elide. I-Nitinol iphinda ikwazi ukugcina iimpawu zayo zomatshini kunye nokuzinza kwiindawo ezinomswakama kunye nezonakalisayo kwaye isetyenziswa ngokubanzi kubunjineli baselwandle kunye nezixhobo zeekhemikhali ukuqinisekisa ukusebenza okuthembekileyo kwiindawo ezinzima.

I-Nickel-titanium alloy spring kwiinkalo ezahlukeneyo zokusetyenziswa:

1. Ukuqina kwentliziyo:

Kutyando lwe-cardiovascular, i-Nitinol isetyenziselwa ukwenza i-stents yentliziyo. I-stent inokucinezelwa ukuya kubukhulu obuncinci kumaqondo obushushu aphantsi, ivumela ukuba ifakwe lula kwimithambo yegazi ngotyando olungephi. Xa i-stent ingena emzimbeni womntu kwaye ichatshazelwa bubushushu bomzimba, impembelelo yenkumbulo ye-nitinol ibangela ukuba ibuyele kwimo esetyenzisiweyo eyoluliweyo, ngaloo ndlela ixhasa udonga lwemithambo yegazi kunye nokugcina umthambo wegazi uvulekile. Xa kuthelekiswa ne-stents yensimbi yendabuko, i-nickel-titanium alloy stents iguquguquka ngakumbi kwaye iyakwazi ukulungelelanisa ngakumbi ukuhamba kwendalo yemithambo yegazi kunye nokunciphisa ukuvela kweengxaki ze-postoperative.
